"He has been very professional in my time at the club and shown a commitment in helping the club turn things around.

"He is moving on and we now need to concentrate on the players who remain at the club."

Former Australian under 17 rep Paartalu will fly out this weekend, ensuring last round's 1-0 loss in Newcastle was his final game for the Roar.

"I can't say that money didn't come into the equation when making this decision because a footballer's career is relatively short and I am still ambitious," Paartalu told The Courier-Mail website.

"Having said this I have a strong desire to continue my football development and believe the new challenge in the Chinese Super League will help take my game to a new level.

"Whilst the past few months have been challenging I've loved my time here at the Roar and leave with fond memories."

It stole the thunder from North's trumpeted arrival.

North has been injected into a Roar side that sits one point clear of dead-last Wellington on the A-League ladder due to nine losses in 16 games.

And Paartalu's departure will only add to the pressure ahead of the Roar's tough home game against in-form Western Sydney Wanderers on Sunday.

North - whose most recent club stint was in December for Japanese outfit Consadole Sapporo - hoped to be the catalyst Brisbane needed to turn their season around.

"Hopefully I bring something different to the team. If it is a bit stale hopefully I can freshen things up a bit by just having a different personality around the training room or on the pitch," North said.

"(And) players come and go, it's part of football - we are all professional.

"Everything they need is here. They have won back to back (titles). They just need to grab it by the scruff of the neck and show who the true champions are."
